GLUlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 474,572, dated May 10, 1892.

Application filed April 24, 1891- $eria1 No. 390,249. (No model.)

board is first coated with a layer of glue- The veneer also is coated with a layer of glue, and then the veneer is laid upon the board and united thereto, as by means of a suitable implement operating to press the veneer upon the board.

In the accompanying drawings, Figure I represents a vertical longitudinal section of a machine embodying my invention. Fig. II represents a plan or top view, partly in section,thereof. Fig. 11" represents a longitudinal section of a supporting-roller. Figs. III and IV represent, respectively, a cross-section of a board to be veneered and a longitudinal section of the leading end of a board used to support the veneer in its introduction to and passage through the machine. Fig. V represents a cross-section of the veneer-supporting board.

Similar letters of reference indicate similar parts.

The letter A indicates the main or gluing roller, and B the pressure-roller, both mounted by means of shafts O in standards D. In practice these rollers are geared together by cogwheels A B to revolve in unison with each other.

At a point below the gluing-roller A is a reservoir E, containing sufiicient of said roller to adapt it to take the glue therefrom, and alongside of this reservoir is a supply-tank F, which is connected with said reservoir by a faucet G for maintaining a uniform supply of glue to the reservoir.

The gluing-roller A is designed to apply a surface coating of glue to the board, as well as the veneer, passing between it and the pressure-roller B, and in order to regulate the thickness of such coating a wiper-roller O is used, the same being arranged in superficial oontactwith the main rollerA, as more clearly shown in Fig. I. A portion of the main roller A is shaped to conform to one surface and the edges adjacent to such surface of the board to be veneered, one form of which board is shown in Fig. III, while the remaining portion of said roller is plain or cylindrical, and the wiper-roller O conforms to the main roller A. At a point opposite to each of said portions of the main roller A is a trough H, extending transversely to the roller-axis, one of which troughs constitutes a guide for the board to be veneered and the other a guide for a veneer-supporting board I, Figs. IV and V. This board I has transverse grooves near its one end, which is the leading end thereof,

to receive the edges of a sliding clamp I, serving to hold the veneer to the board during the process of gluing it, said clamp being fitted to saidend of the board and into the grooves.

The pressure-roller Bis cylindrical as to its effective area, and it is located above the gluing-roller A, with a space between it and the latter approximately equal to the thickness of the board to be veneered.

In applying the machine to use for the purpose of gluing aboard the latteris introduced between the proper portion of the rollers A B by placing it in one of the guide-troughs H. The veneer to be applied to the board is then passed through the machine between the proper portions of the rollers A B by uniting the leading end of the Veneer to the supporting-board I by the clamp I, as indicated in Fig. IV. The veneer is then to be disconnected from the supporting-board I and laid upon and united to the board previously glued. In the repeated use of the veneer-supporting board I it is important that the board shall remain free from glue, and to fulfill this condition the board isformed with a l-ongitudi nal recess I Fig. V, at each edge of the surface thereof receiving the veneer, the effect of these edge recesses being to keep the board entirely out of contact with the gluing-roller. After the board or the veneer leaves the gluing-roller A it is received. on a supportingroller J, the periphery of which is formed of a series of pins, thereby bringing the least portion of said roller in contact with the article.

When the board to be veneered has a groove in one of its edges, as shown in Fig. III, one side of this groove should be coated with glue for securing the veneer which is to be folded into the groove, and to effect this purpose a brush S (shown by dotted lines in Fig. 1-1) is arranged at one end of the gluing-roller A in superficial contact therewith, so as to take the glue from said roller and transfer the glue to the desired part of the groove-namely, in the passageof theboard betweentherollers. The

support for the brush S is a bracket S, which is fastened to one of the standardsD orsome other fixed part of the machine.

What I claim as, new, and desire to secure by Letters Patent, is

1. Amachine for gluing lumber, having, in combination, the gluing-rollerwith a portion thereof shaped to conform to one surface and the edges adjacent thereto; of the board to be veneered, the remaining portion of said roller being cylindrical, the cylindrical pressureroller above the g] Hing-17011613 the wiper-roller in contactwitltthe gluing-roller, and the gluereservoi-r containing the: gluing-roller, the whole. adapted to operate substantially as herein. described, for the purpose set forth.

and the glue-reservoir containing the gluingroller, the whole adapted to operate substantially as herein deseribed,.for the purpose set forth.

3. A machine for gluing lumber, having, in combination, the gluing-roller with a portion thereof shaped to conform to one surface and the edges adjacent thereto of the boardto be veneered,the remaining portion of saidroller being cylindrical, the transverse guide-trough opposite the gluing-roller, the cylindrical pressure-roller above the gluing-roller, the

' Wiper-roller in contact with the gluing-roller,

and the gluing-reservoir containing the gluing-roller, the whole adapted to operate substantially as, herein described, for the purpose set forth.
